摘要： The invention relates to an energy efficient, fast and environmentally favourable process for the preparation of chlorinated butyl rubbers, that uses hypochloric acid (HOCl) and/or dichlorine monoxide (Cl2O) as halogenating agent. The chlorinated butyl rubbers prepared according to the aforementioned process exhibit an advantageous microstructure and a desirable content and ratio of chlorinated and non-chlorinated oligomers and are therefore also encompassed by the invention. The teachings herein also relate to chlorinated copolymers and polymer products that include a chlorinated copolymer.

摘要： A process for producing a halogenated isoolefin copolymer involves contacting an unsaturated isoolefin copolymer cement, the cement containing an unsaturated isoolefin copolymer dissolved in an organic solvent, under halogenation conditions with a halogenating agent and an aqueous solution of an organic peracid oxidant to form a two-phase reaction medium having an organic phase and an aqueous phase, the organic peracid oxidant capable of converting hydrogen halide to free halogen. The process leads to higher halogen utilization even when the cement contains significant amounts of water and without the use of an emulsifier.

摘要： Non-random isobutylene copolymer includes repeat units derived from isobutylene and one or more comonomers selected from isoprene, butadiene, cyclopentadiene, dicyclopentadiene, limonene, substituted styrenes, and C4 to C10 dienes other than isoprene, butadiene, limonene, cyclopentadiene, or dicyclopentadiene, wherein the molar ratio of isobutylene derived repeat units to the comonomer derived repeat units is from 75:1 to 1.5:1. The non-random copolymers have a molecular weight, Mn, of from 200 to 20,000 Daltons and typically have a high double bond content and a high vinylidene double bond content when diene monomers are utilized.

摘要： A copolymer has low levels of cyclic oligomeric compounds, which are undesirable impurities in certain applications. The cyclic oligomeric compounds are provided in an advantageously low ratio of C21/C13 oligomers. The C13 oligomers are extractable using steam to further reduce the total amount of cyclic oligomers. A process for producing the copolymer having low levels of cyclic oligomers involves contacting at least one isoolefin monomer with at least one multiolefin and/or β-pinene monomer in the presence of at least one Lewis acid and at least one initiator in a diluent. The diluent contains a hydrofluorinated olefin (HFO) comprising at least three carbon atoms and at least three fluorine atoms. Hydrofluorinated olefins used in the present invention are better diluents for butyl slurry cationic polymerization than saturated hydrofluorocarbons.
